Description

Technical Field

[0001] This utility model relates to the field of aquaculture tanks, and in particular to an aquaculture tank with a self-cleaning function. Background Technology

[0002] Aquaculture refers to the production process in which aquatic products grow, develop, and reproduce under human intervention, and are harvested periodically. In aquaculture, aquaculture tanks are common aquaculture devices. Round aquaculture tanks are a common type, known for their uniform water flow, high space utilization, and stable structure, making them the most frequently used type of tank in aquaculture. During the process of raising aquatic products in aquaculture tanks, impurities in the water, fish feces, and uneaten feed will accumulate at the bottom of the tank, affecting the water quality and thus requiring regular cleaning.

[0003] Existing circular aquaculture tanks have cleaning mechanisms inside to periodically remove impurities from the bottom, improving water quality. However, these cleaning mechanisms require an external drive source to function. If the drive source malfunctions, cleaning of the tank bottom becomes ineffective, resulting in mediocre performance. Furthermore, the additional drive source increases the cost of bottom cleaning. Utility Model Content

[0004] The main purpose of this invention is to provide an aquaculture tank with a self-cleaning function, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A self-cleaning aquaculture tank includes a tank body, a support base at the lower end of the tank body, and a cavity on the tank body. The bottom surface of the cavity on the tank body is conical. A connecting pipe is provided at the bottom of the tank body, and an oxygenation and cleaning structure is installed on the connecting pipe. The oxygenation and cleaning structure is in contact with the conical surface at the bottom of the cavity.

[0007] Preferably, the oxygenation and cleaning structure includes a connector, a threaded joint, a rotating nozzle body, an air nozzle, a fixed base, a connecting assembly, an inclined plate, and a brush. The connector is installed on the connecting pipe via the threaded joint. The rotating nozzle body and the air nozzle are fixedly connected, and the rotating nozzle body is installed on the connector. The fixed base is disposed on the rotating nozzle body. The inclined plate is installed on the fixed base via the connecting assembly. The brush is fixed on the inclined plate, and the brush contacts the conical surface at the bottom of the cavity of the breeding tank body.

[0008] Preferably, the connecting assembly includes a guide rod, a mounting plate, an adjusting plate, a bidirectional screw, and an adjusting block. The guide rod is fixed to a fixed base, and the fixed base is provided with a sliding groove. The mounting plate is fixedly connected to the adjusting plate, and the lower end of the mounting plate is connected to an inclined plate. The mounting plate is disposed in the sliding groove on the fixed base. The guide rod passes through one end of the adjusting plate. The bidirectional screw and the adjusting block are fixedly connected, and the two ends of the bidirectional screw are respectively threaded to the fixed base and the adjusting plate.

[0009] Preferably, the outer surface of the breeding box body is provided with an annular plate, the lower surface of the support base is fixed with legs, and the legs are arranged in a ring array on the support base, and the end of the connecting pipe is provided with an air inlet pipe.

[0010] Compared with existing technologies, this utility model has the following beneficial effects: This aquaculture tank with self-cleaning function, by setting an oxygenation and cleaning structure on the connecting pipe, and using a rotating nozzle body with an inclined plate and a brush, allows for normal oxygenation of aquatic organisms under normal conditions. Normally, due to insufficient gas pressure, the rotating nozzle body, inclined plate, and brush remain stationary under gravity. When high-pressure gas is introduced, the nozzle sprays out high-pressure gas, and under the reverse thrust of the gas, the rotating nozzle body rotates, carrying the inclined plate and brush. The brush cleans the bottom surface of the aquaculture tank, achieving a self-cleaning effect. The inclined plate is installed using a connecting component, allowing for height adjustment to ensure the brush effectively fits the bottom surface of the tank, guaranteeing cleaning effectiveness. The brush can also be lowered and adjusted after wear, improving ease of use. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-4 As shown, an aquaculture tank with self-cleaning function includes a tank body 1, a support base 2 at the lower end of the tank body 1, and a cavity 3 on the tank body 1. The bottom surface of the cavity 3 on the tank body 1 is conical. A connecting pipe 4 is provided at the bottom of the tank body 1, and an oxygenation and cleaning structure 5 is installed on the connecting pipe 4, which contacts the conical surface at the bottom of the cavity 3. An annular plate 6 is provided on the outer surface of the tank body 1, and support legs 7 are fixed on the lower surface of the support base 2, with the support legs 7 arranged in a circular array on the support base 2. An air inlet pipe 8 is provided at the end of the connecting pipe 4, and a sewage discharge pipe is provided on the tank body 1.

[0018] When using an aquaculture tank, the main body 1 is placed on the support legs 7 of the support base 2. The air source is connected to the air inlet pipe 8, and the end of the air inlet pipe 8 is connected to the connecting pipe 4. After injecting an appropriate amount of water into the cavity 3 of the main body 1, the aquatic organisms to be cultured are placed into the cavity 3 for culture. During the culture process, feed residue, excrement, and other impurities will accumulate on the conical surface at the bottom of the cavity 3. Under normal conditions, the air source provides low-pressure gas, which is delivered to the water in the cavity 3 through the air inlet pipe 8, the connecting pipe 4, and the oxygenation and cleaning structure 5 to oxygenate the water. At this time, the oxygenation and cleaning structure 5 is in a stationary state. When it is necessary to clean the impurities at the bottom, the air source provides high-pressure gas. When the high-pressure gas is ejected from the oxygenation and cleaning structure 5, it generates a large thrust, which rotates part of the structure in the oxygenation and cleaning structure 5, thus cleaning the bottom of the cavity 3 and achieving a self-cleaning effect. The cleaned wastewater is discharged from the drain pipe on the main body 1 of the aquaculture tank.

[0019] According to the above implementation scheme, the oxygenation and cleaning structure 5 includes a connector 501, a threaded joint 502, a rotating nozzle body 503, an air nozzle 504, a fixed base 505, a connecting assembly 506, an inclined plate 507, and a brush 508. The connector 501 is installed on the connecting pipe 4 through the threaded joint 502. The rotating nozzle body 503 and the air nozzle 504 are fixedly connected, and the rotating nozzle body 503 is installed on the connector 501. The fixed base 505 is set on the rotating nozzle body 503. The inclined plate 507 is installed on the fixed base 505 through the connecting assembly 506. The brush 508 is fixed on the inclined plate 507, and the brush 508 contacts the conical surface at the bottom of the cavity 3 on the main body 1 of the breeding box.

[0020] When using the oxygenation and cleaning structure 5, the connector 501 is installed onto the connecting pipe 4 using the threaded joint 502, and the inclined plate 507 is installed onto the fixed base 505 via the connecting assembly 506. During normal use, low-pressure gas enters the rotating nozzle body 503 from the connector 501 and is finally ejected from the nozzle 504 into the water inside the aquaculture tank body 1 to oxygenate the aquaculture. Due to the small back thrust generated by the low-pressure gas, the inclined plate 507 and the rotating nozzle body 503 remain stationary. When cleaning of the bottom of the cavity 3 is required, high-pressure gas is introduced. The high-pressure gas is ejected from the nozzle 504, generating a large back thrust. Driven by the back thrust, the rotating nozzle body 503 rotates, along with the inclined plate 507 and the brush 508. The brush 508 cleans the bottom of the cavity 3, achieving a self-cleaning effect. When the brush 508 wears out, the height of the inclined plate 507 is adjusted by the connecting component 506 so that the end of the brush 508 can effectively contact the bottom of the cavity 3, achieving an effective cleaning effect.

[0021] The connecting assembly 506 includes a guide rod 5061, a mounting plate 5062, an adjusting plate 5063, a bidirectional screw 5064, and an adjusting block 5065. The guide rod 5061 is fixed on the fixed base 505, and the fixed base 505 is provided with a sliding groove. The mounting plate 5062 is fixedly connected to the adjusting plate 5063, and the lower end of the mounting plate 5062 is connected to the inclined plate 507. The mounting plate 5062 is set in the sliding groove on the fixed base 505. The guide rod 5061 passes through one end of the adjusting plate 5063. The bidirectional screw 5064 and the adjusting block 5065 are fixedly connected, and the two ends of the bidirectional screw 5064 are respectively threaded to the fixed base 505 and the adjusting plate 5063.

[0022] When adjusting the height of the inclined plate 507, the double-direction screw 5064 is rotated by the adjusting block 5065. Under the action of the double-direction screw 5064, the adjusting plate 5063 descends along the guide rod 5061, and at the same time, the mounting plate 5062 descends on the fixed seat 505, so that the inclined plate 507 descends with the brush 508, thereby achieving the purpose of adjustment. The structure is simple and the operation is convenient and quick.

[0023] It should be noted that by setting an oxygenation and cleaning structure 5 on the connecting pipe 4, and using the rotating nozzle body 503 to install the inclined plate 507 and brush 508, under normal conditions, external atmospheric pressure gas is introduced into the cavity 3 on the aquaculture tank body 1 through the air nozzle 504 on the rotating nozzle body 503, which can normally oxygenate the aquatic products and ensure their survival rate. Under normal conditions, due to insufficient gas pressure, the rotating nozzle body 503, inclined plate 507, and brush 508 are in a stationary state under the influence of gravity. When high pressure gas is introduced... Behind the body, the nozzle 504 sprays high-pressure gas. Under the reverse thrust of the gas, the rotating nozzle body 503 rotates along with the inclined plate 507 and the brush 508. The brush 508 cleans the bottom surface inside the breeding box body 1, achieving a self-cleaning effect. The inclined plate 507 is installed using the connecting component 506, and its height can be adjusted to ensure that the brush 508 effectively fits the bottom surface inside the breeding box body 1, ensuring the cleaning effect. It can also be lowered and adjusted after the brush 508 wears down, improving ease of use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
